Dowel-like strength from a screw

Dowel-like strength from a screw 

Confirmat-Style Starter Kit
Particleboard and MDF are fine for basic casework, but these man-made materials don’t work well with traditional fasteners. Enter the Confirmatstyle screw: an extra thick fastener that functions like a threaded steel dowel. The reason why Confirmats aren't found in most hardware stores is because they require a special three-stepped hole: a pilot hole, through hole, and a countersink. Good stepped bits are expensive and can be hard to find. But with help from a U.S. manufacturer, Woodcraft now offers a tough, affordable step drill with a replaceable pilot bit. To assemble a joint, align the mating pieces together and drill until the third step of the drill grazes the surface. As the screw draws the parts together, the head should sink just beneath the surface. Attach the cover cap and you’re done. The kit contains everything you need to start assembling cabinets: connecting screws, cover caps, a Pozidrive bit, a step drill, and a replacement pilot bit. Use the 5mm×40mm kit for 1/2" to 5/8" thick materials, and 7mm×50mm kit or 5/8" to 1" thick materials.
